How it works
The text below comes from the sticky notes inside the workflow. We removed links, code samples and anything that looks like a key or token.
STEP 2
Documents vectorization with Qdrant and Google Drive
STEP 3
Create Webhook
- Go to your Meta for Developers App page, navigate to the App settings
- Add a production webhook URL as a new Callback URL
- Verify webhook receives a GET Request and sends back a verification code
- After that you can delete this
STEP 4
RAG System
- Respond webhook receives various POST Requests from Meta regarding WhatsApp messages (user messages + status notifications)
- Check if the incoming JSON contains user message
- Echo back the text message to the user. This is a custom message, not a WhatsApp Business template message
STEP 1
Create Qdrant Collection
Setup notes
The text below comes from the sticky notes inside the workflow. We removed links, code samples and anything that looks like a key or token.
Important!
Configure the webhook nodes this way
- Make sure that both Verify and Respond have the same URL
- Verify should have GET HTTP Method
- Respond should have POST HTTP Method
Configure AI Agent
Set System prompt and chat model. If you want you can set any tools
